METHOD OF AND APPARATUS FOR CONSTRUCTING WALIIS.

Application filed April 13.

To all whom it may concern: I Be it known that I, CHRISTIAN BRYNOLDT,

a citizen of the United States, residing at Pittsburgh, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Methods of and Apparatus for Constructing Walls,of which the following is a specification.

This invention relates toan improved method of and apparatusforconstructing sea and other walls and the like, from material such asconcrete.

One of the primary objects of my invention is the provision of animproved method whereby the construction of such walls may be carriedout more quickly and economically and with less form equipment.

Another object of my invention is the provision of an improved formwhich is collapsible and telescopic outside other forms in place, theforms being so constructed that a new form can be set up withoutdisturbing the form or forms next to it.

Still another ob'ect of the invention re-- sides in the provision of animproved traveler having novel means for supporting the form sections.

My invention also contemplates the provision of form sections soarranged that each form is in effect self sustaining sothat only onetraveler mechanism is needed for a number of forms.

The foregoing, together with such other objects as may hereinafterappear, or are incident to my invention I obtain by means of a methodand apparatus, illustrated in the preferred form in the accompanyingdrawings wherein:

Fig. 1 is anend elevation of my improved traveler with the form sectionsin place; Fig. 2 is a fragmentary side elevation, drawn on an enlargedscale, of that portion of the device shown opposite the line 2--2 ofFig. 1; Fig. 3 is a rear elevation of Fig. 1; Fig. 4 is a plan view ofFig. 3; Fig. 5 is a side elevation of a portion of the rear or backsection of .the form, drawn on an 50 enlarged scale; Fig. 6 is afragmentary lan v view of portions of the rear and front orm sections;Fig. 7 is a section taken on the line 7-7 of Fig. '5; Fig. 8 is anelevation of a detail of my improvements; Fig. 9 is a 1920. Serial No.373,531.

'14 and 15 are enlarged sectional views illustrating details of myimprovement, Figs. 16, 17 and 18 illustrate a modification of myinvention.

Referring first to the improvements in the apparatus for constructingwalls, it will be seen that I employ a traveler, in- A cated as a wholeby the reference letter which is of the. eneral type shown andgenerically claime in my Patent No. 1,298,450, issued 3/25/19. Thistraveler fundamentally consists of an inverted or 'U-shaped frame, theside and top members of which are preferably composed. of structuralsteel members arranged in the form of trusses suitably braced, the sideframes being provided with Wheels 7 riding on rails 8, sup orted in anypreferred manner, as by the oundation or base 9 of the wall. Thetraveler thus straddles the work and is mounted for movementlongitudinally thereof. ../The details of the The wall form consists ofa back form section B; a front form section 0; a detachabletop frame Dfor securing the form sections together when in place; and the bulkheadsclosing the ends of the forms, such bulkheads also being detachable aswill further appear.

The construction of the back wall mold section is illustrated in Figs. 3and 5, from inspection of which it will be seen that such section is aunit comprising a plurality of sheetmetal plates 10, all ofwhich, withthe exception of the plate at one end of the section, have an angle 11at one vertical edge and an angle 12 at the opposite vertical edge; anda pluralit of angles 13 extending longitudinall o the form andriveted inplace. tion has an angle 11 at each vertical edge. A plurality of strongbacks or whalers 14 extend longitudinally of the whole section and serveto bind it into a more or less rigid unit. The angles 11 project abovethe top edge of the section to provide a.

traveler wheels are shown in Figs. 2, 8 and The p ate at one end ofthe-secmeans for attaching the frame B. At the bottom the section isprovided with a Whaler 15.

The front section C is similarly constructed but is specially shaped inorder to give the desired curvature to the front face 1 the requiredwidth of wall, and to inopera ported by tive position away from the wallfor telescoping after the concrete has sufficiently set. It will, ofcourse, be understood that the acks 16 serve to lift the wall formsections in order to permit of collapsing and shifting.

The wall form section C is further supmeans of the jacks 20 and 21exetween the section and the outer leg of the traveler. The frame D issecured to the top of one of the wall form sections, preferab y thesection C.

When the wall sections have been positioned by means of the mechanismjust described, the top frame D will be brought into a position forbolting to the section B. Such frame consists of a plurality of crossstruts 22, the ends of which are adapted to be secured to gusset plates23 on the upwardly projecting portions of the angles 11; and thelongitudinal bracing angles '24 (see Figs. 3, 5, 6, and 7). The frame Dtherefore serves to secure the wall form sections against spreading and,if desired, additional means, such as the tie rods 25, may be employed.Adjustment of the sections as to width is permitted by virtue of theholes in the struts 22.

tending The bulkheads E comprise a suitable frame work 26 secured to theinner face of which, adjacent the vertical edges, are the channels 27,the purpose of which will further appear. Lagging 28 is secured to thebulkhead frames.

The channels 27 are adapted to be secured to the vertical end angles ofthe wall form sections as shown in Fig. 14: and they thus cooperate withthe form sections to mold the wall. They are, therefore, in fact adetachable section of the wall form, and when detached an adjacent formmay be lapped over that portion of the wall molded by the channels 27,the utility of which will be further set forth.

Returning now to in improved method of constructing the wal s,heretofore it has been customary in this art to construct secuseaeaetions of the wall with gaps therebetween,

such gaps being cast a few days later. This method involves stretchingout the work over a considerable distance and also requires a largeamount of form material. I propose to cast the intermediate sectionspractically immediately after the spaced sections have been cast andwhile the concrete is still too green to stand the wash of the waves andforms are, therefore, still in place while the concrete is still green.In car ing out the method I remove the bulkhea s E and the channels 27,and attach to the'ends of the form sections for the intermediate sectionof wall to be cast, angles 29, by means of bolts 30, the free legs ofsuch angles being of such a length as to overlap the exposed portions ofthe adjacent sections of the wall already cast, as shown in Fig. 15. Ithen cast the intermediate section, repeating the operation as manytimes as is necessary for the length of wall to be constructed.

It will be noted that the form for the intermediate sections can bereadily brought in place without interference with the form sectionsalready in place because the forms can be collapsed on the traveler adistance sufii cient to clear the forms already in place. Similarly,after an intermediate section of the wall has been cast, I am enabled toremove the form sections for that portion of the wall already cast whensuch portions of the wall has sufliciently set, leaving the formsections in place about the green sections of the wall. I am thusenabled to keep the Work much less strung out and effect a considerablesaving in time, labor and form equipment, as will be clear from the factthat it is possible by this nfethod to keep a relatively smaller numberof forms practically continuously in use over a relatively shorterlength of wall. The operations are further facilitated by virtue of thefact that each form when all of the parts are in place, is practicallyself sustaining, which frees the traveler for the setting up of newforms in place or the shifting of old forms to a new point of use.

In Figs. 16 to 18, I have shown an adaptation of the foregoing apparatusto the construction of a wall which is provided with laterallyprojecting brackets. The traveler in this instance is substantially thesame as that previously described with the exception that it is providedWith an overhead mixing floor 31 which supports a mixer 32, the travelerbeing further provided on one side with rails 33 for a hoist-ing car orelevator mechanism 34, such rails being supported in a frame 35 bracedoverhead by means of a frame 36 extending to and connected with theupwardly projecting portions of the far leg of the traveler. The car 34is elevated by means of the hoisting cables 37 and when it reaches theupper limit of its travel, it is tilted in the manner indicated indotted lines so as to discharge directly into the mixer 32. p

The wall form sections B and C may be constructed in any referredmanner, such as that already set. fiirth. The brackets are formed bymeans of the bracket forms C secured to the form section C. The sectionB is collapsed for telescoping by means of the jacks 38 and 39, by whichit is also supported in operative position, and the section C with itsbracket mold C'is supported for collapse and telescoping by the jacks 40and 41, there being suflicient clearance to free the form from thebrackets on the wall.

I claim: 1. The herein described process of constructing sea walls andthe like from plastic material such..as concrete which consists in inremoving casting a section with a form,
